JOHN H. CASSERLEIGH, OF DENVER, COLORADO.

DIETAlGI-IAIBLE I-IORSIESHOE.

Application filed .Tune 7, 1913.

To all whom it may concern:

Be it known that I, J OI-IN Cnssnnnnrcn, citizen of the United States, residing at Denver, in the county of Denver and State of Colorado, have invented certain new and useful Improvements in Detachable Horseshoes, of which the following is a specification.

This invention relates to horseshoes and more particularly to that class of shoes which may be readily applied to or quickly removed from either an unshod hoof or over an old shoe, and which is particularly adapted for use in preventing slipping on my pavements and is an improvement u on my prior Patent, No. 1,041,595, dated ctober 22,1912.

A further object of the invention is to provide a shoe of this character which may be so adjusted as to fit boots of different sizes and shapes.

A further object of the invention is to provide a shoe of the character stated, so constructed that it may be applied to the hoof over an old shoe and which is so constructed as to accommodate the calks ol. the old shoe.

A further object of the invention is to provide extension plates at the heel of the shoe which are adapted to be projected to a greater or less extent so as to engage behind the heel calks of an old shoe and rigidly engage these heel calks, these plates being adj-ustable by devices which will prevent the accidental dislodgment or shifting of the extension plates.

A further object of the invention is to provide means whereby the shoe may be laterally contracted and rigldly held 1n its laterally contracted position.

A still further object is to provide means for rigidly supporting heel and toe calks, which means however will readily permit the ready disengagement of the heel and toe calks.

Other objects will appear in the course of the following description.

My invention is illustrated in the accompanying drawings wherein:

Figure 1 is a perspective view of a horseshoe or horseshoe attachment constructed in accordance with my invention. Fig. 2 is a longitudinal sectional view of the construction shown in Fig. 1. Fig. 3 is an under side plan view of the shoe shown in Fig. 2. Fig. 4: is a sectional view on the Specification of Letters Patent.

line 4- 1 of Fig. 3. Fig. 5 is a fragmentary sectional view on the line 5-5 01' Fig. 3. Fig. 6 is a sectional view on the line (56 of Fig. 3. Fig. 7 is a sectional view somewhat similar to Fig. 6 showing the rear end of the shoe section as formed with an open ing 39 for the passage of a heel calk.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawings by the same reference characters.

My improved shoe is formed of two lateral sections designated 2 and 2. These sections are substantially the same in form and the shape of these sections is best illustrated in Fig. 3. Each section has the form of half an ordinary horseshoe. The forward ends of the sections are pivoted to each other, and to this end the section 2 is recessed as at 3 while the section 2 is formed with a projecting ear 4; which overlaps the recessed portion 3 and which is pivoted to the recessed portion by means of the stud 5.

Both of the sections 2 and 2 are formed with a plurality of upwardly projecting ears 6, 6 and 6 as illustrated particularly well in Fig. 1. There are two of these cars at the forward portion of the shoe disposed one on each side of the pivotal junction of the two sections, and there are a pair of cars at the rear ends of each of the sections 2 and 2.

Attached to the ears 6 at the forward ends of the shoe are the upwardly extending braces 7. These braces are inwardlyinclined as illustrated in Fig. 2. Attached to the ears 6 which are higher than the ears 6 or 6 is the upwardly or forwardly inclined band 8. The bands 8 on each of the shoe sections mate with each other and at their forward ends are forwardly turned or bent as at 9 so as to form abutting cars. Passing through these cars is a bolt 10 whereby the ears may be drawn more or less together. Braces 11 are attached to the ears 6 and. ex-

tend upward and are riveted or otherwise at tached to the band section 8. The upper ends of these braces 11 are bent over to form an elongated eye 12 within which is disposed a small bail or ring 13 by which a cruppcr strap or fetlock strap may be applied. It is to be particularly noted at this point that the bolt 10 fits loosely through the cars 9 so that the band sections 8 are practically hinged to each other and may be expanded or contracted in conformity with the cxpansion or contraction of the shoe sections 2 and 2 The sections 2 and 2 are formed rearward of the front of the shoe with transversely extending overlapping portions designated 14 and 15. The portion 15 forms part of the section 2 while the portion let forms part of the section 2. The upper face of the portion 15, is reduced in thickness while the lower face of the portion 1a is cut away so that the portion 14 rests upon the portion 15 and overlaps the same. The portion 1 1 is formed with an elongated slot 16 through which passes a bolt 17 having a head 19, and the confronting faces of the portions 14: and 15 are formed with transversely extending wedgeshaped notches or rililes 18 as shown in Fig. 5 so that when the bolt '17 is tight ened up the two overlapping portions 1st and 15 will be held rigidly engaged with each other but so that when the bolt is loosened the sections 2 and 2 may be laterally expanded or contracted without trouble. It will of course be. obvious that the slot 16 must be slightly curved to permit of themovement of the bolt therein.

It will be noted that there is an elongated slot or opening 20 for the purpose of providing an opening through which the forward calk of an old shoe may project should the hoof to which the improved shoe of the invention is applied be shod at the time of said application.

The rear ends of the shoe sections 2 and 2 are provided with rearwardly projecting ears 21 through which a bolt 22 passes loosely, this bolt being provided with a head at one end and being screw threaded at the other end and provided with a nut 23. Thus the rear ends of the sections may be drawn together and held in any desired adjustment, and after the sections have been so adjusted they may be held tightly by means of the blind bolt 17.

The upper faces of the shoe sections at their rear ends are longitudinally recessed as at 2% (see Fig. 6) these recesses however having a width less than the width of the rear ends of the shoe sections 2 and 2 In these recesses are located the extension plates 25. The confronting faces of the extension plates and of the recesses are toothed, notched or rifiled as at 26. The rear ends of each of the sections 2 and 2 in these recesses 24 are longitudinally slotted as at 27, and

passing through each slot is a bolt or screw 23 as shown 1n Fig. 6 which has screw threaded engagement with the rear end of the corresponding extension plate 25. The

head of this bolt is of course larger than the slot 27 The rear end of each extension plate is provided with an upwardly projecting lug or flange 29 which is adapted to engage behind the heel calk of an ordinary shoe and clamp against this heel calk. It

will be seen that these extension plates may be readily adjusted and may be rigidly held in their adjusted position, and further that this adjustment may be made with relative delicacy. It is further pointed out that because of the fact that the extension plates are provided with triangular wedge-shaped riflies or notches and the bottoms of the recesses are also formed with these triangular or wedge-shaped rifiles, the attachment is not only engaged loosely with the shoe but the extension plates may be wedged into contact with the shoe, the inclined side faces of the teeth wedging against the shoe and causing'a slight forward movement of the extension plate sufficient to clamp tightly against the heel of a shoe as the blind nuts 28 are turned up.

For the purpose of supporting the ealks of the shoe, I provide the forward end of each of the sections 2 or 2 with the downwardly projecting spaced parallel ears 3() and 31 which are formed integral with the corresponding shoe section. The inner faces of these plates converge upwardly and the ears are transversely pierced for the passage of a cotter pin or other holding device designated 32 as shown in Fig. t. The toe calks 33 as shown in Fig. 4 have converging sides so as to fit between the ears 30 and 31 and are pierced for the passage of the cotter pin 32. The base of the toe calk of course rests solidly against the face of the shoe section.

and the toe call: is prevented from withdrawal not only by the pin 32 but by the converging inner faces of the lugs or ears 30 and 31.

The rear calks are supported upon the rear ends of the sections in the same manner as are the forward toe calks, that'is, the rear end of the section 2 or 2 is formed with the parallel downwardly projecting ears 34 and 35. The inner faces of these ears converge downward and are transversely pierced for the cotter pin 36 or other fastening device. The calks 37 are of the same form as the toe calks 33 and gradually converge toward their cutting edges. It will be seen that the calks 33 and 37 maybe readily removed for sharpening or for replacement. It will also be noted from Fig. 2 that the rear end of each of the. sections 2 or 2 is thickened as at 38 to provide for the recesses While the heel calks of an ordinary shoe in place upon a hoof may rest upon the upper faces of the extension plates 25 and abut against the ears 29, I may also provide openings designated 39 in Fig. 7 through which the hind calks may project just as the toe calk of an ordinary shoe may project through the slot 20. The crupper or fetlock strap which extends upward from the rings 13 passes back of the fetlock as illustrated in my prior Patent, No. 1,011,959, of October 22, 1912, and acts to further obviate the may be made to closely fit the contour of the hootf by either expanding or contracting the sections.

Having thus described the invention what is claimed as new is 1. A horse-shoe comprising shoe-sections pivoted to each other at their forward ends, the rear ends of the sections being laterally adjustable, means for holding the rear ends of the sections laterally adjusted with relation to each other, the upper faces of the rear ends of the sections being longitudinally recessed and the face of the recess being transversely riflled, extension plates having upwardly projecting cars at their rear ends fitting said recesses and each having transverse riflles co-acting with the riilles of the recesses, and means for holding said extension plates longitudinally adjusted relative to the shoe-sections.

2. A shoe comprising shoe-sections pivoted to each other at their forward ends to permit the rear ends of the sections to be laterally adjusted, means for holding the rear ends of the sections laterally adjusted to each other, the upper faces of the rear ends 01'' the sections being longitudinally recessed, the bottom of each recess being transversely riilled and formed with a longitudinal slot, extension plates fitting each of the recesses and having upwardly projecting ears or flanges at their rear ends, and an adjusting bolt passing through the slot, the bottom of the recess and into the plate.

In testimony whereof I ailix my signature in presence of two witnesses.
